Finding the ideal temperature settings for your DuPont home can take time and effort. Your heating and cooling system is designed to keep you and your family comfortable at all times. The temperature settings you choose for your home will impact both your comfort and your energy bills. It’s essential to find settings that work well for your needs and are energy-efficient.

This thermostat temperature guide offers tips for enhancing comfort while reducing energy bills with smart thermostat settings. As winter approaches, you’ll want to ensure your home's comfort settings are energy-efficient and provide the warmth you need. 

How Temperature Settings Affect Your Energy Bill

Thermostat settings in DuPont directly impact your monthly energy bill. A larger difference between the indoor and outdoor temperatures requires more energy to heat or cool your home. Keeping the season in mind, along with average outdoor temperatures, will help you predict how high or low your energy bills will be. 

You’ll typically see higher energy bills in the summer and winter when the difference in indoor vs. outdoor temperatures is more significant. To save money on your energy bill, consider using the 10% savings rule. This rule states that you can save up to 10% on your annual heating and cooling bill by setting your thermostat back 7-10 degrees for 8 hours a day.  

Ideal Thermostat Settings for Day and Night

The ideal thermostat settings will depend upon your personal preferences, but in general, there are some best practices to consider. A programmable thermostat enables you to make adjustments and even set a schedule for your HVAC system. 

For winter daytime hours, the recommended thermostat setting is 68°F for heating temperature. If this is too chilly for your liking, try a temperature of 70-71°F. During the summer, the ideal cooling temperature is 78°F. If this is too warm for you, try 76°F for daytime hours. 

During the nighttime hours, you can turn your thermostat settings back a few degrees during the winter. For example, if you keep your home at 71°F during the day, adjust your settings to 68°F for sleeping. Most doctors recommend setting your thermostat to a temperature between 65°F and 68°F overnight . 

Adjusting for Seasonal Changes in DuPont

DuPont has a mild, temperate climate during the warmer months and a cooler and rainy winter season. It’s essential to adjust your thermostat in response to seasonal changes to maintain your home's comfort and energy efficiency. 

As mentioned, the ideal heating temperature is 68°F for most homes. However, finding the sweet spot may take some trial and error. For improved comfort, you can increase the temperature settings by 1 to 2 degrees at a time. 

The ideal cooling temperature is 78°F for optimal energy savings. In DuPont, this temperature may be just fine due to the temperate climate. However, if it’s a bit too warm, try turning down the thermostat by 1 to 2 degrees at a time. 

Smart Thermostats and Zoning Systems

Installing a smart thermostat is one way to improve your energy efficiency in your DuPont home. A smart thermostat is Wi-Fi enabled and automatically adjusts your home’s temperature settings for optimal energy savings. These devices learn your temperature preferences to help you establish a schedule for your thermostat. 

Smart thermostats may automatically adjust temperature settings to save energy when you are asleep or away. These devices make controlling your DuPont home’s temperature settings extremely convenient, thanks to mobile app compatibility. Homeowners can adjust temperature settings on the go via their smartphone. 

Additionally, a zone control system is an energy-efficient HVAC solution that provides precise temperature control in different rooms. A zone control system utilizes thermostats, a control panel, and strategically placed zone dampers to adjust settings according to your behavior. 

Home zoning works with your thermostats to deliver adequate heating or cooling to the rooms in active use. Your HVAC system will provide comfort to the rooms you are actively using, helping you save on energy costs. If you have multiple levels or an expansive floor plan, you may benefit from a zoning system.  

When to Upgrade Your Heating System

Unsure if it’s time to upgrade your heating system in DuPont? Several signs indicate it might be the right time to make changes to your heating system, including:

• It’s over 15 years old. Most heating systems have a lifespan of about 15 years, depending on whether they are a heat pump or a furnace. The U.S. Department of Energy recommends homeowners replace furnaces over 15 years old and heat pumps over 10 years old to prevent failures and promote energy efficiency. 
• Your energy bills have increased. If you’ve noticed your energy bills have steadily increased, your heating system may not be working as efficiently as it used to be. This signals that it’s time to upgrade your home with an energy-efficient heating system. 
• You’re experiencing costly and frequent repairs. If you are experiencing frequent repairs to your heating system, it may be worth considering an upgrade. Repairs can be expensive, and temporary fixes may not be sufficient, whereas a new system ensures reliability. 
• It delivers inconsistent heating. It can be frustrating when a heating system provides inconsistent temperatures. To ensure your comfort, consider an energy-efficient heat pump system. 
• You notice strange noises or odors. Strange rattling noises or foul odors can indicate major problems with your heating system. Have a heating and cooling expert assess your system if you experience unusual noises or smells. 
• If repair costs approach 50% of the price of a new unit. When repair costs become outrageous, you might be better off investing in a new system altogether.

If your air conditioner isn’t cooling like it used to—or if certain rooms in your home feel stuffy while others are freezing—it could be a problem with your AC handler. In the HVAC industry, this is also called an air handling unit (AHU). This part of your HVAC system often goes unnoticed, but it plays a big role in how well your home stays cool and comfortable.

At G&G Heating , we’ve worked with homeowners throughout Olympia and Thurston County who had airflow issues they couldn’t explain—until we checked their air handler. The air handler is typically a large metal box that houses key components like the blower and coil.

In this article, we’ll explain what an AC handler is, how it affects your home’s comfort, and when it might be time to repair or replace it. Air handlers are often installed in locations such as the attic or a dedicated closet for accessibility and space efficiency.

What Is an AC Handler, and What Does It Do?

If your AC system is the heart of your home’s cooling, think of the air handler as the lungs. The process by which the air handler operates involves moving air, regulating flow, and distributing conditioned air to maintain comfort throughout your home.

When it’s running properly, you get strong airflow and consistent temperatures. When it’s not, your system might still be running, but you won’t feel comfortable.

Key Components of an Air Handler

An air handler is made up of several essential components that work together to keep your home comfortable year-round. At the heart of the air handler is the blower motor, which is responsible for moving air through your ductwork and into every room. This steady airflow is what helps maintain a consistent temperature throughout your home.

Another critical part is the evaporator coil. In cooling mode, the evaporator coil absorbs heat from the indoor air, allowing your air conditioning system to deliver cool, refreshing air. When your system switches to heating mode—especially if you have a heat pump—the coil helps warm the air during those chilly Olympia winters.

The air filter is another key player. It traps dust, pollen, and other airborne particles, improving your indoor air quality and protecting the other components inside the air handler. Some air handlers also include heating elements, like electric heat strips, which provide extra warmth during the coldest winter temperatures.

Regular maintenance of these components—especially the blower, evaporator coil, and air filter—is essential. Keeping them clean and in good working order ensures your air handler operates efficiently, delivers high-quality air, and keeps your home comfortable no matter the season.

Importance of Air Filters in Air Handlers

Air filters are a small but mighty part of your air handler, playing a crucial role in both system efficiency and indoor air quality. When your air filter is clean, it allows for optimal airflow, helping your HVAC system run smoothly and efficiently. But when the filter becomes clogged with dust, pet hair, or other debris, it can restrict airflow, forcing your air handler to work harder and use more energy.

A dirty air filter can also lead to common issues like frozen evaporator coils, uneven temperatures, and even system breakdowns. That’s why it’s important to replace or clean your air filter every three months—or more often if you have pets or allergies. Not only does this help maintain your system’s efficiency, but it also keeps the air inside your home cleaner and healthier by reducing airborne contaminants.

How It Affects Airflow in Olympia Homes

Many Olympia homeowners don’t realize that weak airflow or uneven cooling isn’t always caused by the thermostat or outdoor unit. Your air handler plays a huge role in whether cool air actually reaches every room. Balanced air flow is essential for your home's comfort, as it ensures even distribution of conditioned air throughout your living spaces.

Here’s how problems with the handler can show up in your home:

• You hear the system running, but barely feel air from the vents
• Inadequate air flow can prevent treated air from reaching all areas.
• Some rooms stay too warm, while others are cool
• It takes longer than usual to cool down the house

With Olympia’s mix of muggy summer days and damp spring weather, your air handler must be in good shape year-round. When it’s not, your home can feel uncomfortable fast. The air handler is a key part of your heating and air system, ensuring your home's comfort by efficiently distributing treated air to every room.

Energy Efficiency and Air Handlers

Your air handler has a big impact on your home’s energy efficiency. When all components are clean and working properly, especially the air filter and blower motor, your system uses less energy to keep your home comfortable. This means lower utility bills and less strain on your HVAC equipment.

Upgrading to a high-efficiency air handler or pairing your system with a modern heat pump can lead to even greater energy savings. These newer systems are designed to deliver the same level of comfort while using less electricity, making them a smart investment for Olympia homeowners looking to save money in the long run.

5 Signs Your Air Handler Might Be Failing

Air handler issues don’t always start with a loud bang. Sometimes, they show up slowly. Here are five things to watch for:

• Weak or no airflow: If cool air isn’t moving like it used to, the blower motor could be failing.
• High energy bills: A struggling air handler makes your system work harder, which means more electricity.
• Hot and cold spots: Inconsistent temperatures are often linked to airflow issues.
• Banging or rattling sounds: Loose parts, motor problems, or damaged or loose fan blades can cause noises you haven’t heard before. Fan blades should be repaired promptly to prevent further damage.
• AC runs nonstop but doesn’t cool: This is a sign that something deeper, like the evaporator coil or fan, isn’t doing its job. Sometimes, the system may blow warm air due to issues with the evaporator coil or other components.

If any of these sound familiar, it’s time to have your system checked. Problems with the heating system inside the air handler can also lead to inconsistent temperatures and should be repaired by a professional. Schedule your AC repair so we can take a closer look.

Indoor Air Quality and Air Handlers

A well-maintained air handler is key to keeping your indoor air quality high . When your air handler is operating efficiently and your air filter is clean, it helps remove dust, allergens, and other pollutants from the air circulating through your home. This is especially important for families with allergies, asthma, or other respiratory concerns.

However, if your air handler is neglected—if the filter is dirty, the coil is clogged, or there are leaks in the ductwork or drain line—it can spread contaminants and moisture throughout your home. This can lead to mold growth, musty odors, and even health problems for your family.

To protect your indoor air quality, make sure to schedule regular maintenance for your air handler. This includes replacing the air filter, cleaning the evaporator coil, and checking for leaks in the ductwork and drain line. Keeping your air handler in top shape is essential for a healthy, comfortable home environment.

How Olympia’s Weather Can Wear Out Your System

Living in the South Sound means dealing with a bit of everything—rain, humidity, and occasional summer heat waves. That mix puts extra stress on your AC components, especially the air handler. Keeping the air handler clean is crucial to prevent dust and moisture buildup, which can lead to reduced airflow, system failures, and poor indoor air quality.

Over time, moisture and dust can build up inside the unit. If the filter isn’t changed regularly or the system isn’t serviced, that buildup can block airflow and strain the motor.

High humidity levels can make these issues worse by promoting mold growth and further reducing system efficiency. This is one reason why regular maintenance makes such a big difference—it gives your system a chance to keep working before problems show up.

Should You Repair or Replace the Handler?

Sometimes, a quick repair is all your system needs. But if the air handler is older, inefficient, or starting to break down often, replacement might be the smarter choice. We’ll help you weigh the pros and cons based on your home’s needs and the condition of your system.

If you’re noticing airflow problems or rising energy bills, don’t wait for a full system failure. G&G Heating is here to help Olympia homeowners stay cool and comfortable all summer long.

What Is an Air Handler?

Air handlers have a starring role in the heating, ventilation, and air conditioning (HVAC) industry. If you have a ductless mini split system, independent air conditioner, or heat pump, an air handling unit (AHU) is necessary. It circulates heated or cooled air throughout your home, keeping your living space at the desired temperature.

If you want to know more about air handlers and how they work, continue reading for a detailed overview. We also invite you to contact us to schedule an appointment for an estimate if you’re in the market for a new AHU!

How Does an Air Handler Work?

HVAC air handlers help regulate indoor temperatures and control air circulation. Comprising four key components, together they perform essential functions to ensure optimal climate control.

1. The evaporator coil extracts heat and moisture from the air for cooling and warms the air for heating.
2. The blower motor circulates the air using a powerful fan.
3. Sound attenuators ensure quiet operation.
4. Air filters within the AHU enhance indoor air quality (IAQ) and safeguard the equipment from dust accumulation.

Types of Air Handlers

There are three main types of AHUs, including the single-speed model, which features a fan motor that operates at a single, unchanging speed. Then, five-speed air handlers that offer more effective air circulation and quieter operation.

Finally, there are variable-speed handlers that adjust fan speed based on the user's comfort needs. These units use minimal power to maintain your preferred indoor temperature.

What Size Air Handlers Are Available?

Air handlers are available for different spaces based on square footage. An appropriately-sized handler can efficiently distribute air throughout a space without consuming excess energy.

Smaller AHUs are for residential settings and there are different options available. For example, fan coil units are highly energy-efficient and commonly used in residences equipped with pre-existing ductwork.

Residential units are always going to be smaller and less intricate than their commercial counterparts.

A Makeup Air Unit (MAU) is a sizable AHU. They are primarily for commercial and industrial HVAC systems. These units use 100% outdoor air instead of circulating stagnant air that may contain odors and bacteria.

When shopping for an air handler, our team members can inspect your home and help you choose the right size for your current HVAC system. With our assistance, finding the ideal model is easy.

When Is an Air Handler Necessary?

You’ll need an air handler if your home depends on a ductless mini split system, heat pump, or independent AC unit. You do not need an air handler if you have a furnace or radiant heat.

Regardless of what type of heating and cooling system you rely on, G&G Heating and Air Conditioning can help you maintain it. Our highly-trained technicians are here to make sure your home is comfortable all year long without sacrificing efficiency.
